Application filed February 23, ISAE. Serial No. 218,921).

lthe main body of the apparatus by means @if suitable supports and to which'the lining is applied by casting or otherwise, thevchiei object'of the invention being to provide an improved construction ci" apparatus such as 'a tank, pan, retort, mechanical stirrer or like article or structure, for use in manufacturing, storing, treating or transporting chemi- Gals.

According to one feature of the invention the apparatus comprises a main body or structure composed of metal and provided with supports in the `forni 'of perforated metallic sheets which are connected 'to and spaced'at a distance'apart roin-thebody of.

the apparatus and around or within which the'chemical proof 'lining material is adapted t0 be applied. Said supports are constituted by sheets 0f perforated, skeleton or expanded metalwork secured over the entire surfaces to be protected so as to form an interior open metallic lining therefor and so applied as to leave a space of any desired area between the body of the apparatus and the said openworlr metallic lining. Alternatively the main body `or structure of the apparatus is itself composed of expanded metalwork over or within the cells on one side of which a metallic liningl material is adapted to be cast. The metallic lining may be composed of lead, nickehor other metallicl chemical-proof substances. lf desired a material which will serve as a base for the chemical-prooi! lining may vtirst be applied t0 the expanded metalworlr or pressed or` inthe surface thereof :a large number of which :may be inclined Vand .located :in symmetrical rows with their axes disposed in different planes. Alternatively, undercut grooves or :recesses `may .be employed. The holes -`or the like become filled up with the chemical-proof lining and in this manner serve torlrey 4it securely to 'the base material. Where 'al base material is employed the chemical-'proof lining may either bem'etallic orfcomposed of a rmineral substance.

According to another feature'ot the invention and in cases where the apparatus .itself is composed of expanded 4meta'lworlr the sheets or strips of expanded metalworkare carried in metal frames of any suitable size and shape inorderthat7 when 'the chemicalproof lining has been applied thereto, the frames may serve as ystock or standardized units or sections from .which apparatus of any desired size or shape can `be built 'up by Vbolting vor otherwise securing a number of the frames together. ln .practice l prefer first to apply 'to thesaid expanded metal wor-lr a .base layer/of metal 'orf-a metal alloy, ora mineral substance such as cement, yand to yapply the actual mineral vor "metallic chemical-proof lining Sto the said 'base layer.

in lorder that the Isaid invention may be clearly understood Vand readily carried into eiiect the same Vwill now `.be described with reference to the accompanying drawing which shows 'by way of example several constructional forms of 'the invention and in which Figure l is a plan view of 'part vof a stock unit or section constructed according to 'the invention showing the expanded -metalwork and the frame for carrying the same.

Fig. 2 is a. front view 'thereof after the section has been completely l'filled up with a mineral substance and openings formed therein for attaching a metallicor mineral chemical-proof lining thereto.

Fig. 3 is a rear lview y'of a vcomplete'stocl` unit or section after vthe chemical prooi' lining 'has been applied and showing 'the method of assembling the same and;

Fig. i is a cross sectional end view corresponding to Fig. 3. v

Fig. '5 -is -a cross sectional end View of a modified arrangement in which ya metallic chemical proof lining material is applied directly to the expanded or Open metalwork.

Figs. 6 and 8 are cross sectional end views of part of an apparatus and show other methods of attachingthe lining material thereto and Fig. 7 is a face view of the arrangement shown at Fig. 6 and illustrating part of the supports before the chemical-proof lining material has been applied thereto.

Referring to Figs. 1 to 4, l is the frame, 2 is the expanded metalwork attached thereto by means of rivets 3, and 4 is the mineral substance which is employed to fill up the frame and to serve as a base for the actual chemical proof lining material 5 which in the example shown is composed of lead. 6, 6, are the inclined openings in the base material 4 which serve to secure the lining material 5 thereto. The metalwork 2 may be of any desired thickness and formed with any desired size of openings. In the example shown the metalwork 2 is approximately half the depth ofthe frame and is secured thereto so that one of its faces is flush with that face of the frame to which the lead 5 is to be attached. The mineral substance 4. is cast or molded around the metalwork 2, and the inclined openings 6 in the face thereof, as also openings 7 in the rear thereof, are formed therein while the material is still in a semi-plastic condition. The lead 5 s is cast over and around the edges of the section as shown and bolt holes 8 drilled through the frame 1 and the lead. The sections are thereafter placed edge to edge and secured together by bolts and nuts 9, the junctions between the several sections being finally filled up or rendered chemical-proof by fusing the contiguous surfaces of the lead or in any other suitable manner. When the apparatus has been assembled the openings 7 may be filled up with cement or by means of removable plugs, and if desired an outer layer of suitable material 21 of any desired thickness, (as indicated in dot and pick at Fig. 4), may thereafter be applied to the exterior ofthe built-up apparatus. In the arrangement shown at Fig. 5 the base material 4 is dispensed with and the lining` 5 is applied directly to the metalwork 2. The openings in the metalwork 2 as shown are. partially filled with the lining material which extends overthe interior face of the frame and around the edges thereof to any desired thickness. The stock units or sections so made are employed in a similar manner to those illustrated atFigs. 1 to 4. The space 10 when the built-up structure is completed may, if desired, be filled up with concrete applied to any desired degree of thickness, and forming an outer wall for the apparatus. y

Referring to Figs. 6 and 7, 11 is part of the outer supporting wall of an apparatus.

Copies of this patent may be' obtained for five cents each, by addressing the Commissioner of Patents, i

12 is a sheet of open metalwork attached thereto by means of screws 13 and spaced apart therefrom by means of washers 14.

15 is a. layer of mineral substance which is cast or molded around the sheet 12. 16 are inclined openings similar to those shown in Fig. 2 which are formed therein while' the material is in a plastic state and 17 is an outer layer of metal applied to the base 15. In the example shown in Fig. 8, 11 is part of the wall of an apparatus, 18 are keyways formed therein, 19 is a thin basic layer of metallic substance cast into and over the keyways 18, and 20 is a layer of mineral substance, such as chemical-proof cement or sulfur, applied to the metallic substance 19, so as to protect it from deterioration due to continued chemical action thereon. Where a silicious substance or a substance which only melts at such high temperatures that it cannot be applied by u sual means is employed, I may blow the same in powdered form through an oXy-coal-gas, Oxy-hydrogen or Oxy-acetylene flame, or the like either introducing the powdered material into the gases before they leave the burner orifices or directly into the flame so that the protective substance is fused and coated on in one operation, or the material may be blown through an electric arc or arcs with the same result. The material and gases may be preheated. Alternatively, I may apply the powdered substance in a cold state and afterward fuse it.

What I claim and desire to secure by Letters Patent is 1. In apparatus for use in manufacturing, storing, treating, and transporting chemicals, a metallic frame, expanded metal work carried by and located within said frame, a base material supported by said metal work, and a lining of acid-proof material attached to and covering said base material.

2. In apparatus for use-in manufacturing, storing, treating and transporting chemicals, a frame, a foraminous support located within and attachedr to the frame, a base material carried by said support, and a lining of acid-proof material attached to and covering said base material.

3. Apparatus for use in manufacturing, storing, treating and transporting chemicals, comprising a main structure built up from stock units, means for connecting said stock units together, each of said stock units comprising a frame, a foraminous support located within and attached to the frame, a base material carried by said support, and a lining of acid-proof material attached to and covering said base material.
